On December 21, 1946, a single entitled "Let the Good Times Roll" by Louis Jordan (at right on sax) debuted on the Rhythm & Blues charts. The flipside was "Ain't Nobody Here But Us Chickens" (one of my personal favorites). From 1943 until 1950, the Brinkley, Arkansas native's singles topped the R&B chart more than 25% of the time. Fifteen hits crossed over to the pop charts. More information and photos available at the Library of Congress American Memory site on its Today in History page.
